I tried a few different technique with the tyvek. This time I painted the tyvek, placed it over a fabric and quilted it to the timtex then gave it a blast from the heat gun. I haven't discovered anything yet with the tyvek that I would like to incorporate into a quilt, but it sure is fun to play around with. The first two cards, I used a base fabric that I had previously foiled, I like the shinny bits that show through.On this card I used a layer of angelina fibers, not the best results. The Angelina really dulled when I burned the tyvek.
